Solvent isotope effect on sol–gel transition of methylcellulose studied by DSC
Methylcellulose (MC), a hydrophobically modified cellulose derivative, in an aqueous solution undergoes sol-to-gel and gel-to-sol transitions on heating and cooling, respectively. Using differential scanning calorimetry, MC in light (H 2 O) and heavy (D 2 O) water solutions has been investigated to...

| description | Methylcellulose (MC), a hydrophobically modified cellulose derivative, in an aqueous solution undergoes sol-to-gel and gel-to-sol transitions on heating and cooling, respectively. Using differential scanning calorimetry, MC in light (H
2
O) and heavy (D
2
O) water solutions has been investigated to elucidate the solvent isotope effect on the transitions. As a result, their transition temperatures are higher in H
2
O by about 4 °C than D
2
O. This phenomenon is rationalized in terms of the strength of the hydrophobic attractive interaction; the strength is enhanced by D
2
O. We discuss the reason for the enhancement and the difference in the isotope effect between MC and a poly(
N
-isopropylacrylamide) polymer which shows an opposite trend to MC. |
